摘要: Purpose: the objective was to assess efficacy of fast spin-echo (FSE) imaging in detection articular cartilage abnormality osteoarthrosis kneeMaterial and Methods: We studied 356 surfaces 73 knees that had been examined by both MR arthroscopy. images were obtained with FSE (TR/TE 4200/100) on a 0.5 T unit. surface abnormalities detected compared arthroscopic findingsResults: overall sensitivity specificity detecting chondral 60.5% (158/261) 93.7% (89/95) respectively. more sensitive higher grade lesions: 31.8% (34/107) 1; 72.4% (71/98) 2; 93.5% (43/46) 3; 100% (10/10) 4. grades same 46.9% (167/356), differed no than 1 90.2% (321/356) 2 99.2% (353/356). correlation between grading scor...
